Ecologist Ronald Goderie, who launched the breeding programme, told CNN : "We thought we needed a grazer that is fully self-sufficient in case of big predators...and could do the job of grazing big wild areas.

"We reasoned that this animal would have to resemble an auroch."

The team identified auroch descendants and has been breeding certain species together - and breeding the offspring - to get as close as possible to creating a new supercow that matches the ancient herbivore.
